Title: Cylinder block engaging-fixing device to a cam plate type piston pump motor
Inventor: UCHIDA MINORU
IPC: F04B1/22
Filed: 1993-12-22
Abstract: PURPOSE:To provide a cylinder block engaging-fixing device to a cam plate type piston pump motor allowed to be made compact while maintaining the desirable contact state and lubricating state between a cylinder block and a valve plate without increasing the force of pressing the cylinder block to the valve plate and moreover without shortening the spline engaging length between a rotary shaft and the cylinder block. CONSTITUTION:A cylinder block 4 to be engagedly fixed to a spline 3 formed at the rotary shaft 2 of a cam plate type piston pump motor is engagedly fixed in two places including two points B, C of equal distance in the longitudinal direction of the rotary shaft 2 from a position A where the tangential line 16 of the axis 13 of flexure in the direction of the rotary shaft is vertical to the plate face of a valve plate 9. This constitution can prevent the inclination of the cylinder block 4 to the valve plate 9 caused by the flexure of the rotary shaft 2, and there is no seizure between the cylinder block 4 and the valve plate 9 because of desirable lubricity, nor the wear of the spline because of its long length so as to improve durability.

Title: Convergence correction device
Inventor: MISONOO TAKEHIRO
IPC: H01J29/56
Filed: 1993-12-22
Abstract: PURPOSE:To attain effective correction even for a pattern in which mis- convergence quantity is increased only for an intermediate part of a screen and no mis-convergence quantity is increased for upper and lower end portions of the screen by connecting a series circuit comprising a diode and a resistor in parallel with convergence correction coils arranged to generate quadruple magnetic fields. CONSTITUTION:When an output voltage VO from a power supply E is less than a forward voltage of a diode D, the diode D is in an open state, no power supply current IR flows to a resistor R and the current from the power supply E all flows to convergence correction coils L1L2. When the output voltage VO from the power supply E exceeds the forward voltage of the diode D, the diode D is conductive, the impedance of the circuit when viewing from the power supply E is reduced and the inclination of current I is increased. The voltage across the convergence correction coils L1,L2 is lower due to the effect of an equivalent resistance RO and a potential gradient from the power supply IL gets lower. Thus, the objective correction is attained by allowing the power supply E to output nearly a parabolic voltage waveform.

Title: Steam valve
Inventor: SHINDO KURA
IPC: F01D17/00
Filed: 1992-12-04
Abstract: PURPOSE:To prevent a temporary main valve stopping phenomenon caused by such a reason that rear space pressure is reduced more than valve chamber pressure as well as to avoid a turbin trip by flowing steam from a valve chamber into rear space of this main valve when an intercept valve is blocked up. CONSTITUTION:In a combinational reheat valve 5 composed of a reheat steam stop valve and an intercept valve, a main valve 31 of the intercept valve is arranged so as to be capable of contacting/ separating freely with/from a valve seat 32, and a sub valve 34 to open and close this valve hole 33 is arranged above the center of the main valve 31. Leakage steam injected into rear space 45 of the main valve 31 is supplied to a downstream side turbine through the valve hole 33. In this case, a steam passage 46 is formed to connect a valve chamber 30 to receive steam from a bolier to the rear space 45, and an adjusting valve 47 is interposed in the middle of this. When the intercept valve is blocked up, the steam is flowed into the rear spece 45 from the valve chamber 30. Thereby, since a temporary main valve 31 stopping phenomenon is prevented, speedy blocking operation becomes possible.
